The first 140 pages of this book treat of pain in the abstract. Here the author discusses the perception, nature, distribution and intensity of pain and its relation to other sensations. He has made an exhaustive study of the literature on the related subjects from which he often quotes: He is somewhat dogmatic at times, but this makes the subject-matter clearer than if he expressed the conflicting views of the literature. The remainder and greater part of the book discusses the pains which are peculiar to special organs, as the appendix; and to special regions, as pains in the back or head. The author pays particular attention to differential diagnosis of pain and has a number of well-arranged tables on diagnosis. The value of the work is considerably enhanced by many excellent illustrations and diagnostic charts. The book should prove valuable to the general practitioner, both as a reference book
